Periodicals like the WSJ and FT are good for getting the news, but its all pretty superficial. I am not sure you would be learning anything useful for your career. Twitter will get you the news faster in any event.

Some good blogs are FT Alphaville, Sober Look w Walter Kurtz, Calculated Risk w Bill McBride, Carpe Diem w Mark J Perry, Counterparties w Felix Salmon, Abnormal Returns has some decent links but a lot of bullshit as well, Falkenblog, the Epicurian Dealmaker, Mindful Money w shaun michaels for euro info. Lots of other good one that are not coming to mind.

By the way, someone recommended True North by Bill George, and that is another book I read during business school that I would recommend now.

I purposely put off the 4 courses that dealt with ethics and leadership until the end because I thought they would bore me to death. When I signed up for the MBA program, I thought about econ, finance, marketing, investment, etc. It was good timing too as I had just quit my job, probably the most unethical company I can work for. I was able to apply how I was treated along with others to the books like True North, and use that to contrast good companies. Looking back, these courses were probably the best ones in the course. I enjoyed all courses, but I don't really recall all of the formulas and theories I learned from memory.

I'm also taking notes on what others say. Great books can truly influence you in a big way. Sorry to derail the thread a bit, OP.
